3 Claims. (Cl. 29--155.5)

part of the former invention and relates particularly to improvements ina method for securing the telescopically engaged rings against relativemovement and also means for securing the circularly arranged wires withrespect to such rings. According to my improved method I utilize a pairof telescopically engaged or nested rings, one of which has a pluralityof slots or notches therein for the accommodation of wires constitutingthe antenna cage, and to fixedly secure the parts against relativemovement I distort the metal of one of the rings so as to jam or causethe members of the assemblage to tightly contact with one another. Theinvention will 4 5 be fully apparent from the following detaileddisclosure when read in connection with the accompanying drawing andwill be defined with particularity in the appended claims.

In the drawing Fig. 1 is alfragmentary view showing the component partsof the cage-like antenna and the tool for distorting one of the parts;Fig. 2 is a sectional view at right angles to Fig. 1 before the partsare interlocked the telescopically engaging rings being shown insection; Fig. 3 is an enlarged view of a portion of an antenna after themetal of one of the ring members has been distortedyFig. 4 is atransverse section on line 4-4 of Fig. 3; and Fig. 5 is a view similarto Fig. 3 but illustrating slight modification.

Refen'ing in detail to the drawing, the antenna comprises an 'inner ringit formed with a multiplicity of substantially radial notches l2 ofsuitable size to suit the diameter of the multiplicity of wires I4forming the conductors of the antenna cage. An outer keeper ring l6telescopically engages the ring in and in accordance with the presentinvention the internal diameter of the ring l8 makes a relatively loosefit over the exterior of the notched ring In so as to facilitate ease ofassembly.

In accordance with my improved method forming part of the presentinvention after the parts are assembled as shown in Figs. 1 and 2, I

distort the lands of metal l8 lying between the slots l2 preferably bythe use of a tool such as shown in Figs. 1 and 2. This tool comprises apair of jaws 2020 pivotally'mounted at 22-22 on any suitable framemember. Any suitable or well known force means may be utilized to causethe jaws to approach and recede from one another. No claim is made forthe jaw actuating mechanism and therefore the same is not furtherillustrated. A known type of mechanism as used in bolt cutting tools maybe employed. 10 However, one feature of the present invention resides inthe provision of gauge or bottom members 2 4 24 which are adapted to bebrought into contact with the outer periphery of the keeper ring l6 soas to properly position the deforming teeth 2626 for coaction with thelands l8. The

act of causing the jaws 20 to approach one another will deform the metalas shown, for example, in Figs. 3 and 4 by forming recesses 2828 in thelands l8 and causing the bodies of metal 20 3032 to be outwardlydeformed, the bodies 30 jamming against the antenna wires l4 and thebodies 32 closing the space between the outer peripheryof the ring l0and the inner core of the keeper ring I8 thus jamming or interlock g5ing the entire assemblage.

In the modification of Fig. 5 the metal of the lands Ila is distorted ina slightly different manner so as to form overhanging portions 30b whichrestrict the outer dimensions of the slots l2 and 30 which also exercisethe clamping action on the wires. and a wedging action on the keeperring 16a.

While I have described quite precisely certain specific steps in themethod of securing the an- 35 tenna partsand in the tool for distortingcertain of the elements thereof, it is not to be construed that I amlimited thereto since various modifications may be made by those skilledin the art without departure from the invention as defined 40 in theappended claims.

. What I c1aim is:

1. In the making oi antenna cages the method which comprises assemblinga multiplicity of wires in notches formed in a spacing member, 45'

telescopically engaging a keeper member with the latter and distortingthe spacing member thus binding the wires in the notches and jam mingthe assemblage so that said members cannot move relatively to oneanother. 50

2. In the making of antenna cages the method which comprises assemblinga multiplicity of wires in notches formed in the outer face of acircular metal spacing member, fitting a keeper ring over the latter anddistorting the metal of wires in spaced-relationship between the opposedannular faces of a pair of telescopically en a ed rings and distortingone of said rings thus jamming the assemblage and securing the severalparts against relative movement.
